现阶段， 越来越多的终端支持摄像、 拍照、 MP3 , 甚至上网、 看电视、 下载视频节目等功能。 与以前的终端相比， 现有的终端开始釆用功能较强 的处理器作为控制芯片， 能满足一定的数据处理能力， 如现有的智能终端 可达到几百兆的主频。 但是面对多种多样的复杂数据处理业务， 终端的处 理能力还是不能满足用户体验需求， 以无线保真 （WiFi, Wireless Fidelity ) 手机上网为例， 打开一个典型的门户网站的首页常常需要几分钟的时延， 让终端用户难以忍受。 此外， 终端的电池在短期内依然很难有较长的续航 能力， 进行复杂的业务数据处理会将终端的电量在很短的时间内耗尽， 给 用户带来使用上的不便。
另一方面， 随着多核技术的发展， 同样的计算处理能力需要越来越低 的成本， 并逐渐应用于各种应用。 以 3G ( 3rd Generation )月良务和长期演进 ( LTE, Long Term Evolution )等系统中的基站应用为例， 越来越多的数据 和通信协议处理已不是简单的数学算法所能支持的， 更需要相关的包处理 能力， 因此很多基站开始受益于多核技术， 从单核向多核转型， 其合理的 性价比使得基站的处理能力越来越强。
现有技术中， 基站与终端之间釆用穿透模式的数据传输连接模式， 即 基站对从远端节点或是终端来的数据包直接进行穿透处理， 基站作为中转 节点将来自远端节点的数据直接发送给终端， 反之亦然。 在全 IP的基站结 构下，基站和终端之间交互的大都是基于传输控制协议（TCP, Transmission Control Protocol ) /用户数据包协议（ UDP, User Datagram Protocol )连接的 数据包， 在穿透模式下， 以 TCP为例， 终端要负责与其他终端或节点建立 或终止 TCP连接， 对收到的数据包进行确认， 校验和以及序列号的计算， 以及用于拥塞控制的滑动窗口维护等， 这些处理耗费大量的终端计算资源， 并增加了系统响应的延迟。 发明内容

较佳地， 所述基站将数据包发送给远端节点后， 若在 TCP重传超时间 隔内没有收到远端节点发送的确认消息， 则基站重发该数据包直到收到远 端节点发送的确认消息或达到最大重传次数； 所述基站将数据包发送给终 端后， 若在自动重传请求超时间隔内没有收到终端发送的确认消息， 则继 续发送该数据包直到收到终端发送的确认消息或达到最大重传次数。

较佳地， 当确定的数据传输连接模式为代理模式， 且基站收到终端发 出的高层协议类型为 UDP的数据传输连接请求或收到远端节点发出的 UDP 数据包时， 基站的处理过程如下：

本发明的核心思想是， 通过充分利用基站的处理能力， 由基站分担终 端的数据包处理任务， 而终端仅仅对有效的数据负载进行处理， 从而有效 的解决了现有技术中基站对远端节点与终端之间交互的数据包直接进行穿 透处理所带来的终端计算资源被大量耗费、 系统响应延迟增加的问题。
请参阅图 1 ,该图为本发明中通过基站提高终端处理性能的方法的实现 原理流程图， 主要包括如下步骤：
步骤 S10, 确定终端与基站之间的数据传输连接模式；
本步骤中， 终端在进行网络接入或网络重新接入时与基站进行能力协 商确定双方之间的数据传输连接模式。
终端在进行切换时， 服务基站与目标基站协商， 若目标基站支持服务 基站与终端当前的数据连接处理模式， 则服务基站在切换命令中包含该目 标基站， 终端可相应进行网络接入到该目标基站； 否则， 服务基站在切换 命令中不包含该目标基站或指示该目标基站不支持终端与服务基站当前的 数据连接处理模式， 若存在其他的支持终端与服务基站当前数据连接处理 模式的目标基站作为备选， 则终端接入到其他备选目标基站， 否则终端接 入到原目标基站， 通过与其进行能力协商重新建立数据传输连接。 例如： 如果服务基站与终端当前的处理模式为代理模式， 而目标基站仅支持穿透 模式， 则服务基站在切换命令中不包含该目标基站或指示该目标基站仅支 持穿透模式； 如果所述终端还有其他支持代理模式的目标基站作为备选， 则终端接入到该备选的目标基站， 否则终端接入到仅支持穿透模式的目标 基站， 通过与其进行能力协商重新建立数据传输连接。 步骤 Sl l , 在终端与远端节点进行通信时， 终端与基站之间根据步骤 S10中确定的数据传输连接模式创建相应模式的数据传输连接。当确定的数 据传输连接模式为代理模式时， 由基站代表终端对接收到的数据包进行高 层连接处理； 当确定的数据传输连接模式为为穿透模式时， 基站对接收到 的数据包进行转发。
如图 2所示， 所述远端节点为其他终端或是互联网络上的其他节点。 本步骤中， 所述数据传输连接对应的高层协议类型为 TCP或 UDP。 本步骤中， 在终端与基站之间创建穿透模式的数据传输连接时， 终端 与基站之间需交互 QoS信息， 重传参数， 数据包大小， 包头压缩参数信息， 在终端与基站之间创建代理模式的数据传输连接时， 除交互 QoS信息， 重 传参数， 数据包大小， 包头压缩参数信息外， 还需要进一步交互高层数据 连接对应的协议类型，源 IP地址， 目的 IP地址，源端口以及目的端口信息。
当确定的数据传输连接模式为穿透模式时， 基站的处理过程如下： 基 站对接收到的数据包进行 MAC头封装 /去除， 然后转发。
当确定的数据传输连接模式为代理模式， 且基站收到终端或远端节点 发出的高层协议类型为 TCP的数据传输连接请求时，基站的处理过程如下： 基站代表终端与远端节点通过多次握手完成高层数据连接的创建； 基站接收终端发送的仅包含应用数据负载以及媒体接入控制 （ MAC, Media Access Control )包头的数据包， 对其进行分段、 计算校验和、 添加序 列号、 封装 TCP头及 IP头后， 发送给远端节点， 同时， 基站向终端发送确 认消息； 或
基站接收远端节点发送的数据包， 验证其校验和， 若验证成功， 则去 掉数据包的 IP头， TCP头，根据序列号对数据包进行重新组装并封装 MAC 头， 发送给终端， 同时， 基站向远端节点发送确认消息。
基站将数据包发送给远端节点后， 若在 TCP重传超时间隔内没有收到 远端节点发送的确认消息， 则基站重发该数据包直到收到远端节点发送的 确认消息或达到最大重传次数； 基站将数据包发送给终端后， 若在自动重 传请求超时间隔内没有收到终端发送的确认消息， 则继续发送该数据包直 到收到终端发送的确认消息或达到最大重传次数。
当确定的数据传输连接模式为代理模式， 且基站收到终端发出的高层 协议类型为 UDP的数据传输连接请求或收到远端节点发出的 UDP数据包 时， 基站的处理过程如下：
基站接收终端发送的仅包含应用数据负载以及 MAC头的数据包，对其 进行分段、 计算校验和、 封装 UDP头及 IP头后， 发送给远端节点； 或 基站接收远端节点发送的数据包， 验证其校验和， 若验证成功， 则去 掉数据包的 UDP头， IP头， 并封装 MAC头， 发送给终端。
当终端和 /或远端节点希望删除两者之间的高层协议类型为 TCP的数据 传输连接时， 若该数据传输连接为代理模式， 则基站代表终端和远端节点 交互终止高层数据连接， 然后终端和基站之间通过消息交互完成两者之间 的数据传输连接的删除； 若该数据传输连接为穿透模式， 则终端和基站之 间直接通过消息交互完成两者之间数据传输连接的删除。
若终端和 /或基站希望删除两者之间的高层协议类型为 UDP 的数据传 输连接， 则终端和基站之间通过消息交互完成两者之间数据传输连接的删 除。 细的说明。
实施例一
实施例一描述了数据传输连接模式为代理模式时， 基站对终端发起的 TCP数据连接进行处理的情况。
请参阅图 3 , 该图为本发明中数据传输连接模式为代理模式时， 基站对 终端发起的 TCP数据连接进行处理的流程图， 具体过程如下： 终端网络接入或网络重新接入时与基站进行能力协商， 确定双方都支 持数据传输连接的代理模式。 当终端需要与远端节点通信时， 终端首先发 送连接创建请求消息， 基站相应的回复连接创建响应消息。 在创建终端和 基站之间的数据传输连接时， 终端和基站之间除了交互 QoS信息， 重传参 数， 数据包大小等信息外， 还要交互高层数据连接对应的协议类型， 源 IP 地址， 目的 IP地址， 源端口以及目的端口等信息。 基站收到终端的创建数 据传输连接请求后， 判断所述数据传输连接对应的高层协议类型， 如果高 层协议类型为 TCP, 则基站代表终端与远端节点通过多次握手完成 TCP连 接的创建。
TCP 连接的建立可能完成于终端与基站之间数据传输连接建立之前， 也可能完成于终端与基站之间数据传输连接建立之后。 如果 TCP连接建立 完成于终端与基站之间的数据传输连接的建立之后， 则有可能终端已经开 始通过终端与基站之间的数据传输连接发送数据包， 这种情况下， 基站将 接收到的数据包暂时緩存在緩冲区。 由于双方协定的是代理模式， 因此终 端和基站之间传送的数据包仅包含应用数据负载以及 MAC包头，基站与远 端节点完成高层连接创建之后， 基站负责对终端发送的数据进行分段， 计 算校验和， 添加序列号， 封装 TCP头， IP头处理， 并发送至远端节点， 与 此同时， 基站向终端发送确认消息。 如果所述基站在 TCP重传超时间隔内 没有收到远端节点发送的确认消息， 则基站负责重发数据包直到收到远端 节点发送的确认消息或达到最大重传次数， 而不需要终端通过空口重新发 送。
当基站接收到远端节点发送的数据包时， 基站首先验证校验和， 如果 验证成功， 则基站去掉数据包的 IP头， TCP头， 根据序列号对数据包进行 重新组装并封装 MAC头之后， 将数据包发送给终端， 与此同时， 基站对远 端节点发送的数据包进行确认。 终端接收到数据包后， 要对该数据包进行 确认。 如果基站在自动重传请求超时间隔内没有收到终端发送的确认消息， 则基站继续发送数据包直到收到终端发送的确认消息或达到最大重传次 数。
当终端希望删除和远端节点之间的数据传输连接时， 终端向基站发送 连接删除请求消息，基站代表终端和远端节点交互终止 TCP连接， 然后终端 和基站之间通过消息交互完成终端和基站之间的数据传输连接的删除。
本实施例中， 基站负责与远端节点之间的拥塞控制， 消息确认以及滑 动窗口维护， 基站可根据拥塞情况， 动态调整分配给终端的带宽。
实施例二
实施例二描述了数据传输连接模式为代理模式时， 基站对远端节点发 起的 TCP数据连接进行处理的情况。
请参阅图 4, 该图为本发明中数据传输连接模式为代理模式时， 基站对 远端节点发起的 TCP数据连接进行处理的流程图， 具体过程如下：
终端进行网络接入或网络重新接入时与基站进行能力协商， 确定双方 都支持数据传输连接的代理模式。 当基站收到远端节点发出的请求与基站 下属终端创建高层连接的消息时， 基站首先发送连接创建请求消息给终端， 在基站和终端之间的数据传输连接创建过程中， 基站判断所述数据传输连 接对应的高层协议类型， 如果协议类型为 TCP协议， 则基站代表终端与远 端节点通过多次握手完成高层连接的创建。 终端接收到基站发送的连接创 建请求后， 回复连接创建响应消息给基站。 在创建终端和基站之间的数据 传输连接时， 终端和基站之间除了交互 QoS信息， 重传参数， 数据包大小 等信息外， 还要交互高层数据连接对应的协议类型， 源 IP地址， 目的 IP地 址， 源端口以及目的端口等信息。
TCP 连接的建立可能完成于终端与基站之间数据传输连接建立之前， 也可能完成于终端与基站之间数据传输连接建立之后。 如果 TCP连接建立 完成于终端与基站之间的数据传输连接建立之前， 则有可能远端节点已经 开始通过 TCP连接发送数据包， 这种情况下， 基站将接收到的数据包暂时 緩存在緩冲区。
当 TCP连接以及终端和基站之间的数据传输连接都建立之后， 基站对 接收到的远端节点发送的数据包首先验证校验和， 如果校验成功， 则基站 去掉数据包的 IP 头， TCP 头， 根据序列号对数据包进行重新组装并封装 MAC头， 然后将数据包发送给终端， 与此同时， 基站对远端节点发送的数 据包进行确认。 终端接收到数据包后， 要对该数据包进行确认。 如果基站 在自动重传请求超时间隔内没有收到终端发送的确认消息， 则基站继续发 送数据包直到收到终端发送的确认消息或达到最大重传次数。
同样的， 由于双方协定的是代理模式， 终端向基站发送的数据包仅包 含应用数据负载以及 MAC包头。基站接收到终端发送的数据包后， 负责将 终端发送的数据进行分段， 计算校验和， 序列号， 封装 TCP头， IP头， 并 发送至远端节点， 与此同时， 基站向终端发送确认消息。 如果所述基站在 TCP 重传超时间隔内没有收到远端节点发送的确认消息， 则基站负责重发 数据包直到收到远端节点发送的确认消息或达到最大重传次数， 而不需要 终端通过空口重新发送。
当远端节点希望删除和终端之间的数据传输连接时， 远端节点向基站 发送 TCP连接终止请求消息， 基站代表终端和远端节点交互终止 TCP连接， 然后终端和基站之间通过消息交互完成终端和基站之间的数据传输连接的 删除。
本实施例中， 基站负责滑动窗口维护， 并根据拥塞情况， 调整分配给 终端的带宽。
实施例三 实施例三描述了数据传输连接模式为代理模式时， 基站对终端发起的
UDP数据连接进行处理的情况。
请参阅图 5 , 该图为本发明中数据传输连接模式为代理模式时，基站对 终端发起的 UDP数据连接进行处理的流程图， 具体过程如下：
终端进行网络接入或网络重新接入时与基站进行能力协商， 确定双方 都支持数据传输连接的代理模式。 当终端需要与远端节点通信时， 终端首 先发送连接创建请求消息， 基站相应的发送连接创建响应消息。 在创建终 端和基站之间的数据传输连接时， 终端和基站之间除了交互 QoS信息， 重 传参数， 数据包大小等信息外， 还要交互高层数据连接对应的协议类型， 源 IP地址， 目的 IP地址， 源端口以及目的端口等信息。 基站收到终端的创 建数据传输连接请求后， 判断所述数据传输连接对应的高层协议类型， 如 果高层协议类型为 UDP, 则基站发送创建数据传输连接响应消息给终端。
终端接收到创建数据传输连接响应消息后， 开始发送仅包含应用数据 负载以及 MAC 包头的数据包给基站。 基站负责将终端发送的数据进行分 段， 计算校验和， 封装 UDP头， IP头， 并发送至远端节点。
如果基站接收到远端节点发送的数据包， 基站首先验证校验和， 如果 校验成功， 则基站去掉数据包的 IP头， UDP头， 并封装 MAC头， 将数据 包发送给终端。
在终端和基站希望删除两者之间的数据传输连接时， 终端和基站之间 通过消息交互完成两者之间数据传输连接的删除。
实施例四
实施例四描述了数据传输连接模式为代理模式时， 基站收到远端节点 发出的 UDP数据包后进行处理的情况。
请参阅图 6, 该图为本发明中数据传输连接模式为代理模式时，基站收 到远端节点发出的 UDP数据包后进行处理的流程图， 具体过程如下： 终端网络接入或网络重新接入时与基站进行能力协商， 确定双方都支 持数据传输连接的代理模式。 当基站收到远端节点发送给基站下属终端的
UDP数据包时， 基站首先发送连接创建请求消息给终端， 终端接收到基站 发送的连接创建请求后， 回复连接创建响应消息给基站。 在创建终端和基 站之间的数据传输连接时， 终端和基站之间除了交互 QoS信息， 重传参数， 数据包大小等信息外，还要交互高层数据连接对应的协议类型， 源 IP地址， 目的 IP地址， 源端口以及目的端口等信息。
当终端和基站之间的数据传输连接建立之后， 基站对接收到的远端节 点发送的数据包首先验证校验和， 如果校验成功， 则基站去掉数据包的 IP 头， UDP头， 并封装 MAC头， 然后将数据包发送给终端。
同样的， 由于双方协定的是代理模式， 终端向基站发送的数据包仅包 含应用数据负载以及 MAC包头。基站接收到终端发送的数据包后， 负责将 终端发送的数据进行分段， 计算校验和， 封装 UDP头， IP头， 并发送至远 端节点。
在终端和基站希望删除两者之间的数据传输连接时， 终端和基站之间 通过消息交互完成两者之间数据传输连接的删除。
相应于本发明上述方法， 本发明进而提出了一种提高终端处理性能的 基站， 请参阅图 7, 该图为本发明中提高终端处理性能的基站的结构框图， 其主要包括连接模式确定模块、 连接创建模块和数据包处理模块， 其中， 各个模块的主要作用如下：

本发明实施例通过基站分担终端的高层连接处理任务， 大大提高了终 端包处理的性能， 通过减少重传以及缩减包头传输的方式大大减少了空口 开销， 在增强用户体验的同时， 达到节电的目的。
显然， 本领域的技术人员应该明白， 上述的本发明实施例的各步骤可 以用通用的计算装置或计算装置可执行的程序代码来实现。 本发明不限制 于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于 本领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精 神和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明 的保护范围之内。
